History

Original series

Jessie received Ekans already captured for chūgen before she met Ash. It is unknown who it was a gift from.

As an Ekans

Arbok first appeared in Pokémon Emergency! as an Ekans. WThrowing their Poké Balls down from their Meowth balloon, Jessie and James used both it and James's Koffing to quickly overtake the defenseless ViridianPokémon Center. Koffing's job was to create a SmokeScreen while Ekans destroyed the computers. Chasing everyone into the back room, Ekans scared away the Pokémon that were sent out by Ash, which causes Misty to decide to battle Team Rocket. This is a failed effort, however, as both of them manage to catch up to Ash in no time at all. Just then, Nurse Joy's Pikachu come out and heal Ash's Pikachu with a Thunder Shock attack, while at the same time attacking the Team Rocket. Giving Ash's Pikachu enough power to stand up, Ash charged-up Pikachu using Misty's charred bike, and he let him have his own Thunder Shock. As the group are being electrocuted, Koffing releases a stream of Smog from one of the craters on its body, and the electricity climbs up the toxic gas, causing the entire Pokémon Center to explode, and sending Team Rocket blasting off.

Although Arbok lost nearly every battle, as is traditional for Pokémon owned by Team Rocket, it has occasionally been shown to have extraordinary power and endurance to match its massive size. For example, in The Misty Mermaid, Arbok was able to single handedly battle Horsea, Starmie, Squirtle and Seaking underwater (where water Pokémon have the advantage) without the help of Weezing, enduring a huge amount of offense and eventually cornering all its opponents for the victory before Seel evolved into Dewgong and defeated it with Ice Beam.

Advanced Generation series

In A Ruin With A View, Jessie sent out Arbok alongside James' Weezing to battle Team Magma grunts who approached them. Not long after coming out of their Poke-Balls, Team Magma's Houndoom used Roar to send Arbok and Weezing back into their Poke-Balls.

In A Poached Ego!, Team Rocket found a poacher holding a herd of Ekans and Koffing captive in Hoenn. After freeing them, James and Jessie reluctantly ordered Arbok and Weezing to stay in the wild and guard their fellow Pokémon. The two Pokémon have not been seen since.

Jessie and Arbok shared a close bond, as demonstrated when Arbok refused to leave her at first and cried when it finally did.

Personality and characteristics

Arbok and Weezing seem to be both very emotional. This was first shown in Island of the Giant Pokémon, where they got very sad for being separated from Jessie and James, crying desperately, with Pikachu trying to cheer them up. At the end of the episode, when every lost Pokémon got reunited with their partners, Ekans and Jessie, along with James and Koffing, were happily crying, while Ash was only smiling with Pikachu, which may mean that Jessie's bond with Arbok was stronger than Ash's bond with Pikachu. It was also in this episode that it explained to Meowth along with James's Koffing "Pokémon do bad things because master bad. Pokémon not bad." In Lights, Camera, Quacktion both Arbok and Weezing got depressed for being rejected as the main characters in the movie. It was only with Jessie's and James's help that they got over it. On their last appearance, in A Poached Ego!, they were reluctant in leaving Jessie and James, and when they did, they strongly cried.

Trivia

Jessilina and her Arbok-shaped flute

Arbok's arrow-like pattern on its neck differs in some episodes. Sometimes, the ends of the arrow stretch until the ends of its eye-like patterns on its chest and is only a few inches wide. Similarly, there are two red dots on its arrow in some episodes and in other episodes there are none.

In The Misty Mermaid, Jessie's Arbok was shown to be able to swim without the need for air.

Its gender was hinted in the Japanese version of Island of the Giant Pokémon. In the subtitles, it refers to itself and Koffing as おれたち ore-tachi, which is a pronoun normally used by males meaning "we", also used by characters such as Ash, Brock and James in the Japanese version.

Out of all Pokémon ever owned by Jessie or James, Arbok has used the most moves, with eleven.

Arbok, as an Ekans, was one of two Pokémon to be the first Poison-type Pokémon owned by main characters. This is due to it debuting simultaneously alongside James's Koffing.
